Improvement in combined harrow and cultivator



WILLIM J. FUNK, OF PORTLAND, OREGON, ASSIGNOR TO HIMSELF AND HARRISON B. OATMAN, OF SAME PLACE.

Letters Patent No. 92,714, dated July 20, 1869.

IMPROVEMENT IN COMBINED HARROW AND CULTIVATR.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, WILLIAM J. FUNK, of the city of Portland, in the county of Multnomah, in the State of Oregon, have invented ,a new and useful machine, a Harrow and Oultivator combined, and supposed to be an improvement; and the following, I do hereby declare, is a true and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, and figures and letters ofA reference marked thereon.

Figure 1 is a perspective view;

Figure 2, a side elevation Figure 3,3. plan; and

Figure 4, a detached view ofthe bent axle supporting the frame of the machine.

The machine consists, generally, of two triangular frames, one within another, .the outer one, A, constituting the frame, on which are secured, to either side, two lugs of metal, O, fig. 4, which have a hole traversing them vertically.

Into this hole a bent rod, d, is inserted, and fastened by a screw, e.

This bent rod forms one of the axles, on which the wheels-of themachine are placed, they being alike on each side.

When the machine is used as a cultivator, the vbent rods d are inserted on the under side, 'as the teeth of the eultivator arel longer than the teeth of the harrow, and differ in length about as much as the vertical part of the rod (l is long;

. When the machine is used as a barrow, the cultivater-teeth are taken out, by disengaging the hookshaped latches 1), seen in the plan at g. 3, and ,the bent rod d is loosened and put in from the upper side of the lugs C, and fastened with the screw e, as before.

By this means the frame A is lowered, so that the barrow-teeth strike the ground, and are then in a position for work.

So'much for the outer frame A, on which are placed the levers G and H, which raise and radjust the height of the cultivator and barrow-frame B,.which is held in position by the pins in pin-holes O, in one of the rods J, operating against the lever G from the front, by reason of the weight of the harrow and cultivatorframe B. v

The lever G is held in vplace by the semicircular cog-bar M, which is firmly fastenedto the frame A.

The lever H is fastened to .the axle of one of two crank-bars R, and is connected with the rear crankbar by one of the rods J', and as it is thrust forward or backward, the frame B rises and falls.

The levers E and F operate the toggles K, which are used where rows of corn, or other products, are crooked, as is often found to be the ease in corn or potato-fields.A

It' the driver finds such a row approaching him, and his machine likely-ttov plow it up, he pulls vone or both the levers to\\ 'a1d"`him,- which throws the toggles -rearward, and' thus narrows his machine and allows it Vto pass through, without injuring his crop.

This part of the machine is believedl to be an improvement ou any cultivator now in use.

This narrowing and widening allow the operator to do just as he pleases, without turning his team either to the right or left.

In so turning his team, he isvliable to trample as the frame B is actuallyl hung on the crank-rods R,

which act as a .common draught by a chain, unless the pins are in the holes O, onthe rod J', thus making it'rgid like other cultivators.

' Neither of the crank-rods R moves laterally, but their ends are in the outer frame-A.

Onthe rear crank-redit, a longpiice, T, swivels, having a collar on each side of it" around the crankrod', and on the end ,between the collars is a pin, on which the inner ends of the toggles turn.

The rear end of this piece T rests in a slot, N, on the under side of the back-piece, in. the frame B.

This slot allows the' right side of the frame B to traverse toward the left, without interfering with the piece T, which holds one end ofthe toggles K.

Another tenoned slot, S, lhas a similar use when the left side or end retreats toward the centre.

(It should have been said before, that the frame B is hinged at the front by a hinge, Q.)

On the under side of either the right and left piece of the frame B, are two slots L, in which the crankrods Il. are placed, and admit of the movement above described, viz, from side to side.

The letters I represent the barrow-teeth, and letters l) the cultivator-teeth, and it becomes a cultivator when they are in, or a harrow when they are out, subject to the changes described before.

It is believed that the foregoing parts are new and useful improvements.

What I claim, is-

2 1. The eulvtivator and burrow-frame B, as con- 4. In combination, the frame B, frame A, toggles structed, and arranged in combination with the main K, crank-rods R, levers E and F, rods J J, lever frame A. H, rod J', mld latches P, :mil as constructed and ar- 2. The toggles K, in combination with crank R, ranged. levers E and F, and rods J J. WM. J. FUNK.

3. In combination with the cultivator and harrow- \Vitnesses: frame, cultivator and barrow-teeth, the lat-ches P, for S. L. MAs'rERs,

the purposes specified. NVM. H. PAYNE.
